MEANS- FOR DRYING AIR IN MINES.

Application filed June 25, 1926, Serial No. 118,606, and in Germany-July 1, 1925.

As itis well known, the hot temperature of the air in mines and itsgreat amount of moisture are'injurious to the miners working capabilityand health. All-attempts to remedy this, are limited to provisions fordecreasing the temperature. It is true that it has also been proposed toabsorb the moisture from the air but only for the purpose only of makingthe cooling ofthe air by l0 rinsing with water more effective.

The present invention relates to improved means for decreasing theamount of moisture of the air in mines with the aid of water-absorbingsubstances, such as calcium l5 chloride (0e01,), magnesium chloride(MgCl or the like, for the purpose of making the miners'more able towork without injuring their health. To this end, the water-absorbingsubstances are disposed" in broad layers in a closable receptacle'at theworking-places where the air is to be dried, said receptacle beingopened at the beginning of the shift, so that the air can come incontact with the water-absorbing substances, and again closed at thetermination of the shift, in order to avoid an unnecessary consumptionof material and a drying-out of the walls in the mines.

Preferably, a mine truck can be used for the purpose in question,such-as illustrated by way of example on the accompanying drawing, in aSaid truck perspective side view thereof. 1 is closed all around whileits two end walls 2 are hinged thereto so that they can be opened. Inthe interior of the plates 3 are h posed fashion, substances as a truck,a plurality of detachable perforated orizontally arranged in superonwhich the water-absorbing re placed in broad layers. The

lowermost parts 2 of the two end walls 2 are integral with the truck, sothat at the bottom of the latter a collector 4 is formed,

into which flows the water absorbed by, and mixed with the salts of,said substances. A tap 5 at the bottom of said collector serves tolet-off the water from time to time. 6

indicates a closure for keeping the end walls 2 closed.

What I claim, is

Apparatus for drying air in mines with tion thereon stances.

In testimon my hand.

of broad layers of said sub-- y whereof I have hereunto set KARLBRUNZEL.
